	The temperature portion of the Time/Temp Display uses a Thermistor
	Probe to sense oven temperature. The thermistor outputs a resistance
	proportional to the oven temperature. This resistance is then converted by
	the display into a temperature reading.
AUTOMATIC COOL DOWN	When the oven reaches operating temperature the normally open Oven
	Cool Down Thermostat closes. After the oven is switched OFF, the Ther
	mostat bypasses the Fan Switch, keeping the Cooling Fan and Main Fan
	in operation until the oven cools down to approximately 200°F (93.3°C).
